magnetic field calculationThe formulae for calculating the magnetic field produced by the finite size helical coil with rectangular cross section [J. Todoroki: Kakuyugo Kenkyu 57 (1987) 318] are extended to the case with an arbitrary polygonal cross section. The formulae for the calculation of ...
Here, B0=ωB/α is the magnetic field at the centre of trap, ωB is the cyclotron frequency, α=q/m is the particle's charge-to-mass ratio and z0 the distance between coil and centre. Note that (28a), (28b), (28c) is not a valid approximation of a mirror trap's magnetic fiel...
Here we show an extreme, uniaxial magnetic anisotropy and the emergence of magnetic hysteresis in Li2(Li1 À xFex)N. An extrapolated, magnetic anisotropy field of 220 T and a coercivity field of over 11 T at 2 K outperform all known hard ferromagnets and single-molecular magnets. Steps ...
Mechanical Behavior Analysis of Model Coil for the 40-T Hybrid Magnet Superconducting Outsert A 40 T hybrid magnet system will be designed and constructed at the High Magnetic Field Laboratory, Chinese Academy of Sciences. The superconducting outser... JW Zhu,YN Pan,WG Chen,... - 《IEEE ...
A case of particular interest is the one where the material is subject to a cyclic field of frequency f, with the field and the average magnetic induction B in the material remaining co-linear during the process. Then the time integral [1]W=?HdBdtdt over one magnetization cycle gives the...
and ion thermal diffusivity in the discharge, where the direction of the NB injec- tion (NBI) is switched from co-injection to counter-injection (parallel to anti-parallel to the equivalent plasma current, which gives the poloidal field produced by the external coil current) at t ¼ 5.3 ...
TECHNICAL FIELD The present disclosure relates to a magnetic recording medium and a cartridge. BACKGROUND ART Tape-shaped magnetic recording media have been widely used to store electronic data. In a tape-shaped magnetic recording medium, it is desired to reduce the height of irregularities on the...
USA) was used to excite the field through the coils, and thez-component oscillating magnetic field near the sample was inductively measured by a lock-in amplifier (Signal Recovery 7270, AMETEK Inc., Santiago, CA, USA) through a 4-mm-diameter coil prober made of 80-turn copper wire loops...
Exposure to magnetic field (MF) can affect cellular metabolism remotely. Cardio-toxic effects of Doxorubicin (DOXO) have limited clinical uses at high dose. MF due to its effect on reactive oxygen species (ROS) lifetime, may provide a suitable choice to boost the efficacy of this drug at lo...
Phantom experiments and simulations proved its efficiency and sensitivity, but the susceptibility of the method to field inhomogeneities is still not well understood. In this study, we simulated and analyzed the dynamic of three spin-lock preparations and their response to field inhomogeneities in the...
